Industrial Applications

This compound functions primarily as a blowing and gelling catalyst in polyurethane systems. Its balanced reactivity profile enables controlled foam rise and cell structure development, making it indispensable in formulations requiring consistent physical properties and processing stability. As a specialty intermediate, it is not used directly in final consumer products but plays a critical role in industrial-scale polymer manufacturing.

Key advantages include:

  • Enhanced foam uniformity and resilience
  • Compatibility with a wide range of polyol and isocyanate systems
  • Stable performance under standard storage and handling conditions

Handling and Storage

Store in a tightly closed container in a cool, dry, well-ventilated area away from heat, sparks, open flames, and incompatible materials such as strong oxidizers or acids. Use appropriate personal protective equipment during handling. Packaging is typically 25 kg per drum, with custom options available upon request.
